The high field magnetization of DyAg, which is an antiferromagnet with three successive magnetic transitions at TN=56 K, T2=49 K and T1=46.5 K, has been investigated up to 54 T by using pulsed magnet for the magnetic field applied along ,  and  axes. At low temperatures below T1, for H||, a saturation of the magnetization is observed after four metamagnetic jumps and the saturated moment is obtained to be 9.7 μB/Dy. The magnetic phase diagrams have also been established in detail for the three axes with the complementary studies of the magnetic susceptibility and the specific heat. The obtained phase diagrams below 40 K are well consistent with the previous results for all the directions. Above 40 K, on the other hand, the present results reveal an existence of some new phases in the proximity region of TN.
